Subject: Question about netns & AF_UNIX

Hi, again a question about netns...

I seem to recall being able to use AF_UNIX sockets across network name
spaces, but I cannot reproduce that with a current kernel. Probably my
test was fubar (I've lost the script).

In any case: is a design decision to forbid this, even when the file
system is shared? I found some discussions from 2008, but I don't see
an agreement being reached...

I also wonder if filedescriptor passing thru ancilliary messages will
work (that is, with unix sockets that I've created before the netns
change).

Thanks
